Abstract

Example multi-channel display systems are disclosed. An example apparatus includes at least one processor to execute instructions to at least in response to determining that a first display controller is to provide at least a first portion of video data on a first channel, provide a first control signal to the first display controller instructing the first display controller to provide the at least the first portion of the video data on the first channel, and in response to determining that a second display controller is to provide at least a second portion of the video data on a second channel, provide a second control signal to the second display controller instructing the second display controller to provide the at least the second portion of the video data on the second channel, the second channel different from the first channel.

Claims19

Dependent claims

A multi-channel controller configured to:

provide a channel select waveform to a first display controller and to a second display controller, the channel select waveform having a first waveform feature and a second waveform feature, wherein the first waveform feature is a rising edge or a falling edge;
and
the channel select waveform configured to:
instruct, cased on the first waveform feature, the first display controller to provide at least a first portion of video data on a first channel;
and
instruct, based on the second waveform feature, the second display controller to provide at least a second portion of the video data on a second channel, the second channel different from the first channel;
whereing the video data includes a first video frame and a second video frame, the first waveform feature is a rising edge and the second waveform feature is a falling edge, and the multi-channel controller is configured to instruct:
the first display controller to provide the first video frame on the first channel in response to the rising edge, and
the second display controller to provide the second video frame on the second channel in response to the falling edge.

6 more elements

A system comprising:

a first display device;
a first display controller coupled to the first display device;
a second display device;
a second display controller coupled to the second display device;
and
at least one processor coupled to the first display controller and to the second display controller, the at least one processor configured to:
provide video data to the first display controller and to the second display controller;
and
provide a channel select waveform to the first display controller and to the second display controller, the channel select waveform having a first waveform feature and a second waveform feature;
wherein the first display controller is configured to, responsive to receiving the first waveform feature the channel select waveform, instruct the first display device to display at least a first portion of the video data;
and
wherein the second display controller is configured to, responsive to receiving the second waveform feature of the channel select waveform, instruct the second display device to display at least a second portion of the video data;
wherein the video data includes a first video frame and a second video frame, the first waveform feature is a rising edge and the second waveform feature is a falling edge, the first display controller is configured to display the first video frame on the first display device in response to the rising edge, and the second display controller is configured to display the second video frame on the second display device in response to the falling edge.

10 more elements

A method comprising:

providing, by at least one processor, a channel select waveform to a first display controller and to a second display controller, the channel select waveform having a first waveform feature and a second waveform feature, wherein the first waveform feature is a rising edge or a falling edge;
and
the channel select waveform configured to:
instruct, based on the first waveform feature, the first display controller to provide at least a first portion of video data on a first channel;
and
instruct, based on the second waveform feature, the second display controller to provide at least a second portion of the video data on a second channel, the second channel different from the first channel;
wherein the video data includes a first video frame and a second video frame, the first waveform feature is a rising edge and the second waveform feature is a falling edge, the method further comprising:
displaying, by the first display controller, the first video frame on a first display device in response to the rising edge;
and displaying, by the second display controller, the second video frame on a second display device in response to the falling edge.
